Advanced search

Advanced search is divided into two main parts, and one or more groups in each of the main parts. The main parts are the "Search for" (including) and the "Remove from search" (excluding) part. (The excluding part might not be visible until you hit "NOT" for the first time.) You can add new groups to both the including and the excluding part by using the buttons "OR" or "NOT" respectively, and you can add more search options to all groups through the drop down menu on the last row (in each group).

For a result to be included in the search result, is it required to fit all added including parameters (in at least one group) and not fit all parameters in one of the excluding groups. This system with the two main parts and their groups makes it possible to combine two (or more) distinct searches into one search result, while being flexible in removing results from the final list.

The maximal number of hits you can export is 250. When you want to export more records please use the Create feeds function.

Prolonged computer use, especially if fatigue ensues, is associated with visual and musculoskeletal symptoms. The aim was to determine the time-course of perceived fatigue in the wrist, forearm, shoulder and eyes during a 60-min mouse task (painting rectangles), and whether object size and/or mouse use demands were of influence. Also, we investigated performance (number of rectangles painted), and whether perceived fatigue was paralleled by local muscle fatigue or tissue oxygenation. Ten women performed the task for three conditions (crossover design). At condition 1, rectangles were 45 × 25 mm, square paint cursor size 1.3 × 1.3 mm, and mousepointer movement ratio 1:26. At condition 2, the same cursor size and mousepointer movement ratio was used, but rectangles were smaller. At condition 3, the smaller rectangles were used, but the cursor size was also smaller and mousepointer movement ratio was 1:8. The results showed increased self-reported fatigue over time, with the observed increase greater for the eyes, but no change in physiological responses. Condition 2 resulted in higher performance and increased eye fatigue. Perceived fatigue in the muscles or physiological responses did not differ between conditions. In conclusion, computer work tasks imposing high visual and motor demands, and with high performance, seemed to have an influence on eye fatigue.

The overall aim was to study transgender persons’ experiences of, and reactions upon, attitudes and social norms in relation to their gender identity. Another question that was relevant to answer was how transgender persons are affected by the hetero norm. The method used to collect data was through questionnaires published on the internet. The only requirement to participate was to be a transgender over 18 years old, and when the survey closed, 35 respondents had answered it. The questionnaire consisted of both quantitative and qualitative questions. Collected data were analyzed using descriptive statistics and content analysis.

The results indicate that transgender persons living conditions are largely affected by norms, and that they encounter a considerable amount of negative attitudes due to their gender identity. To "pass" as either man or woman turned out to be something that made it easier for transgender people to evade negative attitudes.

One hope is that this study can provide knowledge to different instances in the community to open up to be more open to critical thinking around norms.

The conclusion was that persons with a transgender identity are affected by societal norms and by heteronormativity. It takes a lot of courage to be able to be one self but everything boils down to how strong a person are and the availability of support and role models in the surrounding society.

BACKGROUND: Socioeconomic status (SES) can greatly affect the clinical outcome of medical problems. We sought to assess the in-hospital mortality of patients with the acute coronary syndrome (ACS) according to their SES.

METHODS: All patients admitted to Tehran Heart Center due to 1(st)-time ACS between March 2004 and August 2011 were assessed. The patients who were illiterate/lowly educated (≤5 years attained education) and were unemployed were considered low-SES patients and those who were employed and had high educational levels (>5 years attained education) were regarded as high-SES patients. Demographic, clinical, paraclinical, and in-hospital medical progress data were recorded. Death during the course of hospitalization was considered the end point, and the impact of SES on in-hospital mortality was evaluated.

CONCLUSIONS: This study found that patients with low SES were at a higher risk of in-hospital mortality due to the ACS. Furthermore, the results suggest the need for increased availability of jobs as well as improved levels of education as preventive measures to curb the unfolding deaths owing to coronary artery syndrome.

Diverse ethnic groups may differ regarding the risk factors and severity of coronary artery disease (CAD). This study sought to assess the association between ethnicity and CAD risk and severity in six major Iranian ethnic groups.

Methods

In this study, 20,165 documented coronary artery disease patients who underwent coronary angiography at a tertiary referral heart center were recruited. The demographic, laboratory, clinical, and risk factor data of all the patients were retrieved. The Gensini score (an indicator of CAD severity) was calculated for all, and the risk factors and severity of CAD were compared between the ethnical groups, using adjusted standardized residuals, Kruskal–Wallis test, and multivariable regression analysis.

Results

The mean age of the participants (14,131 [70.1%] men and 6034 [29.9%] women) was 60.7 ± 10.8 years. The Fars (8.7%) and Gilak (8.6%) ethnic groups had the highest prevalence of ≥4 simultaneous risk factors. The mean Gensini score was the highest for the Gilaks (77.1 ± 55.9) and the lowest among the Lors (67.5 ± 52.8). The multivariable regression analysis showed that the Gilaks had the worst severity (β 0.056, 95% CI 0.009 to 0.102; P = 0.018), followed by the Torks (β 0.032, 95% CI 0.005 to 0.059; P = 0.020). Meanwhile, the Lors showed the lowest severity (β −0.087, 95% CI −0.146 to −0.027; P = 0.004).

Conclusions

This study found that there was heterogeneity in CAD severity and a diverse distribution in its well-known traditional risk factors among major Iranian ethnic groups.

Background: Given gender differences in the risk of coronary artery disease (CAD), the present study sought to investigate these dissimilarities amongst patients who underwent angiography at a major, tertiary heart hospital in Iran. Methods: Between 2005 and 2010, 44,820 patients who underwent coronary angiography were enrolled in a registry. Pre-procedural data such as demographics, CAD risk factors, presenting symptoms, and laboratory tests, as well as postprocedural data were collected. The data were, subsequently, compared between the men and women. Results: Out of the 44,820 patients (16,378 women), who underwent coronary angiography, 37,358 patients (11,995 women) had CAD. Amongst the CAD patients, the females were not only significantly older, less educated, and more overweight than were the males but also had higher levels of triglyceride, cholesterol, low-density lipoprotein, highdensity lipoprotein, and fasting blood sugar (P< 0.001). Of all the risk factors, hypertension and diabetes mellitus showed the strongest association in our female CAD patients (OR=3.45, 95%CI: 3.28-3.61 and OR=2.37, 95%CI: 2.26- 2.48, respectively). Acute coronary syndrome was more prevalent in the men (76.1% vs. 68.6%, P< 0.001), and chronic stable angina was more frequent in the females (31.4% vs. 23.9%, P< 0.001). With respect to post-procedural recommendations, the frequency of recommendations for non-invasive modalities was higher in the females (20.1% vs. 18.6%, P< 0.001). Conclusion: Hypertension and diabetes mellitus had the strongest association with CAD in our female patients. In the extensive CAD patients, medical treatment was recommended to the women more often.

Sedentary behavior in children is positively associated with an increased risk of both obesity and insulin resistance. Children spend a considerable portion of their awake time in sedentary behavior; however, the pattern of accumulation is not known. Thus the objective of this study was to describe the patterning of sedentary behavior of children at and away from school.

Design and Methods:

The patterns of sedentary time in a sample of 53 children (28 girls) aged 10-12 years during school-term time were examined. Children wore an accelerometer for 1 week. Total sedentary time, prolonged sequences (bouts) of sedentary time, and frequency of active interruptions to sedentary were examined on school days and weekends and within school time and non-school time on school days.

Results:

The data did not support our hypothesis that children accumulated more sedentary time on school days when compared with weekend days (mean [SD]: 64.4% [5.3] vs. 64.9% [9.0], P = 0.686). However, when comparing school time with non-school time on school days, children accumulated more sedentary time at school (66.8% [7.3] vs. 62.4% [5.2], P < 0.001) and spent more time at school in sustained sedentary sequences, that is, uninterrupted sedentary time for 30 min or more (75.6 min [45.8] vs. 45.0 min [26.8], P < 0.002). The children also recorded less breaks per sedentary hour within school time when compared with non-school time (8.9 h−1 vs. 10.2 h−1, P < 0.001).

Conclusion:

Reducing total sedentary time spent both in and out of school remains an important challenge. Interrupting sedentary time more often in the “working” (school) day could also reap important musculoskeletal and metabolic health rewards for children.

Meal at school is a part of the school studies and it is important for health, but is also a prerequisite for both learning and enjoyment. The school meal can provide students an opportunity to recover from their studies but sometimes students perceive the meal situation as stressful. It is important that the food environment at school works well for school children, so they do not have to rush during the meal and they can get the opportunity to eat in peace. The purpose of this study was to investigate how students perceive lunch break at school. If they feel they get enough time to eat and how they feel during the meal situation in the school restaurant. The research approach of this study was qualitative and the method of data collection was focus groups. Data were analyzed as a content analysis. The aim of the study were secondary school students in grade 7 and 9, one class from each grade was selected. The study was conducted at a secondary school in a municipality in Sweden with approximately 210 000 inhabitants. The results of the study show that students at secondary school feel they have enough time to eat lunch, but the lunch break is too short. The meal environment in the school restaurant is perceived as very messy and stressful. The meal situation was experienced as more stressful at grade 7 students than 9th grade students. The conclusion was that students need longer lunch break and meal environment is perceived as stressful.

Background: Human error and deficient non-technical skills (NTSs) among providers of ALS in helicopter emergency medical services (HEMS) is a threat to patient and operational safety. Skills can be improved through simulation-based training and assessment. Objective: To document the current level of simulation-based training and assessment of seven generic NTSs in crew members in the Norwegian HEMS. Methods: A cross-sectional survey, either electronic or paper-based, of all 207 physicians, HEMS crew members (HCMs) and pilots working in the civilian Norwegian HEMS (11 bases), between 8 May and 25 July 2012. Results: The response rate was 82% (n=193). A large proportion of each of the professional groups lacked simulation-based training and assessment of their NTSs. Compared with pilots and HCMs, physicians undergo statistically significantly less frequent simulation-based training and assessment of their NTSs. Fifty out of 82 (61%) physicians were on call for more than 72 consecutive hours on a regular basis. Of these, 79% did not have any training in coping with fatigue. In contrast, 72 out of 73 (99%) pilots and HCMs were on call for more than 3 days in a row. Of these, 54% did not have any training in coping with fatigue. Conclusions: Our study indicates a lack of simulation-based training and assessment. Pilots and HCMs train and are assessed more frequently than physicians. All professional groups are on call for extended hours, but receive limited training in how to cope with fatigue.

There is an increased global interest in occupational health across small businesses as they represent a large share of employers in many societies. In the model of healthy work organisations, employee health is a prerequisite for higher productivity and profitability and management practices are considered as determinants of organisational health. A better understanding of how managers in effective companies use their time can offer a better understanding of how this can affect employees’ well-being and business effect-iveness. Managers’ long working hours and share of time spent on Management by Walking Around (MBWA) are considered important characteristics of managers’ work that might have consequences for employees’ and managers’ own health outcomes, as well as for organisational effectiveness. MBWA is a management technique common for successful companies in regard to their effectiveness; providing an opportunity for a spontaneous manager-subordinate interaction that might be important for employee health and wellbeing. Studies of managerial work have to some extent not clearly placed managers’ time use in the broad context of leadership, often missing to link it with leadership behaviour theories, health and effectiveness.

Objective

The objective of this study was to explore, on the one hand, the total amount of working hours that managers spent, and on the other, their patterns of time allocation to different activities in effective SMEs. Research questions were: 1) What patterns regarding managers’ working hours can be identified across socio-demographic variables, leader-ship experience factors and leadership profiles in effective SMEs? 2) What patterns regarding proportions of total working hours spent on MBWA can be identified across socio-demographic variables, leadership experience factors and leadership profiles in effective SMEs?

Method

The study used data collected within the project, “Successful Companies in Gästrikland”. Annually the project nominates 120 companies for the award based on companies’ financial indicators. The study employed a cross-sectional design and analysed responses to questionnaires collected within the project during years 2014-2018. The inclusion criteria were small and medium sized companies (more than four and less than 250 subordinates), high-level managers having subordinates. Data analysis were carried out using descriptive statistics and regression analysis.

Results

The results section is being processed and will be reported on the conference.

The study aim was to investigate effects of mental activity, accompanied by mu-rhythm depression, on recuperation after physical fatigue. In a study participants performed 11 one minute bouts of static hand grip intermitted by 2 minutes rest pauses. During pauses participants watched video with either dynamic hand grips (biological movements) or deformation of geometric figure (control). Obtained data showed there was a significant depression of mu-rhythm during biological movement's observation. There was significant fatigue of subjects in an exercise with physical activity, but there was no reliable influence of performed mental activity on recovery after fatigue.

Objective: The purpose of this study was to investigate whether there was any association between participation in cultural activities and sense of coherence among seniors living in two nursing homes.

Methods: A questionnaire based on Antonovskys SOC-13-questionaire was used, with added self-formulated questions including gender, age, level of physical function and participation in cultural activities. The questionnaire was distributed to 76 people 65 years and older without dementia at two nursing homes in central Sweden and 40 respondents answered the questionnaire. The material was processed and analyzed in the statistic computer program SPSS, where descriptive statistics were prepared and a chi-square analysis and logistic regression analysis was performed.

Results: No statistically significant relationship between participation in cultural activities and sense of coherence could be seen. However, there was a correlation between the level of function and SOC scores. The lower level of function, i.e. the more help the respondent needed in everyday life, the lower sense of coherence.

Conclusion: Functional level seems to have greater impact on an individual's sense of coherence than participation in cultural activities in the given study population.

The purpose of this study was to determine if wellness benefits led to any changes in exercise habits among employed postmen. The study was a cross-sectional study carried out by a quantitative method. The collection of data took the form of a questionnaire. The sample consisted of 30 postmen employed at a post office in northern Sweden. The results show that of the postman who use health care benefits, there has been a relatively small change in exercise habits. The results also show that consistently for all respondents was health the main motivation factor for exercise. Time aspect was a factor for not using the wellness benefits. The study showed a state of health is the primary motivational factor to exercise both for those using health care benefits and for those who do not use them.

Work motivation has shown positive effects on job satisfaction and well-being. Research reports that personality explained some part of what motivates employees. The purpose of this study was to investigate whether the same results could be see on the Swedish labor market. The study measured background factors, motivation through the work values ​​questionnaire (WWQ) and personality through the ten item personality inventory (TIPI). 128 full-time employees answered the survey. The results showed significant correlations for security and conditions (MF1) with personality, gender and education level. Personal development and stimulation (MF3) significantly correlated with personality and employment. A multiple regression analysis showed that agreeableness, gender, age and education level contributed to the explained variance in MF1. Extraversion contributed to the explained variance of MF3. The same results were found in this study as in earlier research, personality traits and background factors stands for a part of the explained variance in motivation.

Title: Older people's experiences of exercise training: a survey based on a descriptive design.

Course: Public Health: Theory and method of application and degree, 30 credits. University of Gävle, health education program.

Author: Helena Andersson

Purpose: According to earlier research the western population is aging. This may affect, the older peoples`s physical disability in one form or another. The consequences may be that the need off care can increase. However elderly can prevent a variety of age-related diseases by being physically active. The study will examine how older people view physical activity and participation of other social activities. This is to improve understanding of older people's health and what can be done in the future.

Method: The study was conducted using a qualitative approach, in which four semi-structured interviews were conducted with older adults who exercise regularly. The interviews were based on a thematic interview guide with specific themes that gave informants space to talk freely about the issues raised. The sample consisted of three women and one man where the youngest was 63 and the oldest 74 years old.

Results: Exercise was the highest priority of this group of people. It was in the connection with social interaction that the exercise became complete according to the informants. The place for exercise was found to be important; to train with others, seemed to generate joy, power, energy and motivation. This meant that all informants were rarely sick, which also was something that was pointed out. They exercise to obtain more healthy years.

The aim of this study was to explore if young women aged 18-20 years experienced that Instagram affected their body image, their physical activity and their eating habits in relation to the phenomenon orthorexia. The method for the study was a qualitative content analysis based on semi-structured interviews with four young women with the age of 18-20 years old. The results showed that Instagram affected young women's body image, their physical activity and their eating habits. Primarily body image and physical activity were most affected, eating habits were less affected. The results showed that there were both a positive and a negative impact, but by far a negative impact. Respondents experienced feelings like anxiety and guilt when, for example, a training session did not go as planned or after they had eaten an unhealthy meal. Their mindset and emotions that came forward in the results were partly linked to the phenomenon of orthorexia. The young women were adversely affected by the pictures and videos on Instagram and also by other social media. They exposed themselves to develop mental and physical ill health. Society should consider prioritizing the young women to prevent them from falling into the mindset that is similar to the phenomenon of orthorexia.

Aim: The aim of the study was to compare food-, sleep-, and physical activity habits among high school students in relation to morning- or evening type (Chronotype). Methods: In a cross-sectional study data were collected by use of a questionnaire comprising 24 questions concerning the participants´ food-, sleep-, and physical activity habits. The questionnaire was distributed to 77 students. A total of 77 (100%) individuals, 41 males and 36 females, participated in the study. Data were analyzed by descriptive statistics and comparative chi-square test. Results: Students were divided into two groups; morningtypes (n= 23) and evening types (n= 54). Morningness was associated with sufficient sleep and sleep of good quality during weekdays compared with eveningness. Morning types also tend to eat breakfast more often before school than evening types. Evening types showed a higher physical activity level. Conclusions: Chronotype was associated lifestyle among students in vocational secondary school year one. Early school start does not benefit adolescents that are evening types and it has a negative impact on sleep- and food habits.

26. Not getting used to the smell – Chemical intolerance as lack of habituation

Andersson, Linus

Chemical intolerance is a prevalent, medically unexplained symptom characterized by diverse symptoms following weak chemical exposure. The symptom-eliciting exposures are often odorous, and include perfume, fabric softeners and fragrant flowers. Several explanatory mechanisms have been proposed, but empirical data is scarce. By reanalyzing data from previous studies, we aimed to find a criterion for chemical intolerance based on reactions to actual chemical exposure.

Method:

We grouped participants from six previous studies based on their pattern of habituation to weak olfactory (amylacetate and n-butanol) and trigeminal (CO2 and acrolein) compounds. In two studies utilizing event-related potentials, and one functional magnetic resonance imaging study, stimuli were presented intranasally using a dynamic olfactometer. An exposure chamber that allowed full body exposure was used in the remaining three studies.

Results:

Individuals who did not habituate to weak chemical exposure, compared with those who did, reported (1) increasing symptoms during the course of the exposure, (2) greater problems with odors in everyday life, and (3) greater levels of everyday distress. They (4) performed worse on cognitively demanding tasks during exposure, and differed in measures of (5) the autonomic nervoussystem(respiratoryrateandpulseratevariability),(6)low-level inflammation and oxidative stress, and (7) the so called pain matrix of the brain.

Discussion:

Lack of habituation to weak chemical exposure may be a fruitful method of defining a sub-group of chemical intolerance.

PURPOSE: Multiple chemical sensitivity (MCS) is a prevalent medically unexplained symptom characterized by symptom reactions to everyday chemical exposure below hygienic thresholds. The aim of this study was to investigate the expressions of hyper-reactivity in MCS during whole-body exposure to low concentrations of the odorant n-butanol.

METHODS: We exposed 18 participants with MCS and 18 non-ill controls to a low concentration of the odorant n-butanol using an exposure chamber. The first 10 min constituted blank exposure, after which the n-butanol concentration increased and reached a plateau at 11.5 mg/m(3).

RESULTS: MCS participants, compared with controls, reported greater perceived odor intensities, more unpleasantness to the exposure and increasing symptoms over time. MCS participants also expressed higher pulse rate and lower pulse rate variability than controls did. No group differences were found for breathing rate or tonic electrodermal activity responses.

CONCLUSIONS: We conclude that MCS sufferers differ from healthy controls in terms of autonomic responses, symptoms and chemosensory perception during chemical exposure.

Chemical intolerance is a medically unexplained affliction that implies deleterious reactions to non-toxic everyday chemical exposure. Sensitization (i.e. increased reactivity to repeated, invariant stimulation) to odorous stimulation is an important component in theoretical explanations of chemical intolerance, but empirical evidence is scarce. We hypothesized that (1) individuals who sensitize to repeated olfactory stimulation, compared with those who habituate, would express a lower blood oxygenated level dependent (BOLD) response in key inhibitory areas such as the rACC, and higher signal in pain/saliency detection regions, as well as primary and/or secondary olfactory projection areas; and (2) olfactory sensitization, compared with habituation, would be associated with greater self-reported chemical intolerance. Moreover, we assessed whether olfactory sensitization was paralleled by comparable trigeminal processing – in terms of perceptual ratings and BOLD responses. We grouped women from a previous functional magnetic imaging study based on intensity ratings of repeated amyl acetate exposure over time. Fourteen women sensitized to the exposure, 15 habituated, and 20 were considered “intermediate” (i.e. neither sensitizers nor habituaters). Olfactory sensitizers, compared with habituaters, displayed a BOLD-pattern in line with the hypothesis, and reported greater problems with odours in everyday life. They also expressed greater reactions to CO2 in terms of both perceived intensity and BOLD signal. The similarities with pain are discussed.

29. Highlighting the large variation in perceived properties of odors over time

Individuals differ considerably when rating the perceived properties of odors, especially over time. A second glance at previously published data-sets from our laboratory revealed that the same invariant exposure often produced both floor and roof effects. An odor that at the end of the exposure ses-sion was regarded as non-existent by one participant, could border the “absoulte maximum” rating category in another. We provide re-analyses from four exposure studies where we illustrate the perceptual variability over time, and outcomes associated with such ratings. We note that high, compared with low ratings of odor intensity over time is associated with ratings of unpleasantness and symptoms, but also with everyday distress, cognitive performance, autonomous nerv-ous system activity and deviating responses in the so-called pain or saliency matrix of the brain. We bring an open ques-tion to ECRO regarding how this considerable variability should be interpreted, and what the consequenced are for research and for setting exposure limits.

A widely held view is that top-down modulation of sensory information relies on an amodal control network that acts through the thalamus to regulate incoming signals. Olfaction lacks a direct thalamic projection, which suggests that it may differ from other modalities in this regard. We investigated the late positive complex (LPC) amplitudes of event-related potentials (ERP) from 28 participants, elicited by intensity-matched olfactory, auditory and visual stimuli, during a condition of focused attention, a neutral condition, and a condition in which stimuli were to be actively ignored. Amplitudes were largest during the attend condition, lowest during the ignore condition, with the neutral condition in between. A Bayesian analysis resulted in strong evidence for similar effects of task across sensory modalities. We conclude that olfaction, despite its unique neural projections, does not differ from audition and vision in terms of task-dependent neural modulation of the LPC.

The purpose of this study was to describe the prevalence of self-reported visual and neck/shoulder complaints among individuals with a low vision diagnosis. The study also aimed to examine whether there was an association between the degree of self-rated visual and the neck/shoulder complaints. There was a questionnaire survey that was conducted on patients that visits an eye center in a county in central Sweden. There were a total of 18 people participated in the survey, between 17-92 years old. The questionnaire contained 22 questions and was analyzed with SPSS. The results showed how the distributions of answers were to the questions about the respondents’ vision respectively of respondents’ musculoskeletal problems. Results also showed that there was an association between the degree of self- rated visual difficulties and the degree of self- rated neck/shoulder disorder. The results in this study support the hypothesis that a relationship exists between visual and musculoskeletal problems.

The concept of healthy workplace has been defined as an organization that maximizes the integration of worker goals for wellbeing and company objectives for profitability and productivity. Conditions in today’s working life make new approaches necessary in order to limit negative health effects of work and to enhance wellbeing and health at work. About 24 % of the working population in Sweden report to have had work-related disorders during the last twelve months. In order to achieve a sustainable working life it is likely that strategies and actions from different and new angles are needed.ObjectivesThe present study is a part of a larger study (the GodA –study; a Swedish acronym for good work environments and healthy workplaces) and aims to investigate how work environment factors, work ability, work motivation, work and life balance predict well-being at work.

Methods

The GodA study is a 2-year follow up study in Sweden with a survey feedback design in three companies with both blue- and white collar workers. One of the companies serves as “intervention-company”, the other two as controls. A baseline questionnaire was sent out 2013 and the results from the survey were reported back to the companies, which have been processing their results. In spring 2015 a follow up survey has been administered. Data have been analysed with univariate and multivariate linear regression analyses.

Results showed that not only work environment factors are important predictors. To maintain a healthy work place a promotion of balance between work and private life is needed.

The concept of healthy workplace has been defined as an organization that maximizes the integration of worker goals for wellbeing and company objectives for profitability and productivity. Conditions in today’s working life make new approaches necessary in order to limit negative health effects of work and to enhance wellbeing and health at work. About 24 % of the working population in Sweden report to have had work-related disorders during the last twelve months. In order to achieve a sustainable working life it is likely that strategies and actions from different and new angles are needed.

The present study is a part of a larger study (the GodA –study; a Swedish acronym for good work environments and healthy workplaces) and aims to investigate how work environment factors, work ability, work motivation, work and life balance predict well-being at work.

Methods

The GodA study is a 2-year follow up study in Sweden with a survey feedback design in three companies with both blue- and white collar workers. One of the companies serves as “intervention-company”, the other two as controls. A baseline questionnaire was sent out 2013 and the results from the survey were reported back to the companies, which have been processing their results. In spring 2015 a follow up survey has been administered. Data from the baseline measurements have been analysed with univariate and multivariate linear regression analyses.

Results

A baseline multivariate linear regression model, which included background factors, perceived psychosocial work climate and work environmental factors (motivation, leadership, employee responsibilities, efficacy, work ability and management committed to employee health) and work life balance, showed that psychosocial work climate (B= .48, 95% CI=.27 – .69) leadership, (B= .27, 95% CI=.05– .49), work ability (B= -.12, 95% CI= .03 – .21), motivation (B= -33, 95% CI= .14 – .51) and work life balance (B= -.34, 95% CI=-.57– -.12), were significantly associated with well-being at work and explained 40% of the variance (Adjusted R2=.40, p<.001). Results from the two-year follow up will be presented at the conference.

Conclusions

Results showed that not only work environment factors are important predictors. To maintain ahealthy work place apromotion ofbalancebetween workand private life is needed.

35. Changes in physical workload with implementation of mouse-based information technology in air traffic control

University of Gävle, Centre for Musculoskeletal Research. University of Gävle, Faculty of Health and Occupational Studies, Department of Occupational and Public Health Sciences, Occupational health science.

Effects on physical workload were quantified when introducing new information technology in air traffic control. Seven female and seven male air traffic controllers were studied in an old control system, and during simulated - but similar - work in a new, mouse-based system. Postures, movements and muscular load were recorded (inclinometry for head, neck, back and upper arms; goniometry for wrists; electromyography for the trapezius and forearm extensor muscles). The new system was associated with lower movement velocities than the old one (examples; [50th percentiles] head flexion: 2 vs. 5 o/s, P<0.01; right arm elevation: 3 vs. 6 o/s; P<0.01; [90th percentile] wrist flexion: 19 vs. 50 o/s, P<0.01), less varying postures (head: 95th-5th percentile range 17° vs. 34o; P<0.01), and less muscular rest in the right forearm extensors (3.5 vs. 9% of time; P<0.05). The old/new system differences were amplified at high work intensities. The new air traffic control system caused a major change of physical exposures, probably associated with an increased risk of musculoskeletal disorders in arms and hands.

Relevance to industry

While this study concerned the specific changes in the introduction of a new air traffic control system, we believe that the findings are applicable to similar technological developments in other settings.

The aim of this article is to describe a design and implementation of a school-university action research project about teaching and learning biology and mathematics in primary school. Nine teachers in grades 1 to 6, in collaboration with two researchers, were using content representation (CoRe) in learning study (LS)-inspired cycle as pedagogical tools when planning, implementing, and reflecting on lessons and pupil learning. By using pre- and post-tests, the teachers acquired knowledge about pupil subject-specific knowledge and learning. Some examples are given on how the tools in the project influenced the teaching practices and pupil learning. This research design brought together university and school practitioners to work collaboratively in a professional learning community, which developed teaching and learning in biology and mathematics.

The purpose of this study was to describe experiences and perceptions of ongoing work with health promotion cultural inserts in four different associations in Gavle municipallity for asylum seekers and newly arrived children and adolescents. The method used was a descriptive empirical qualitative interview with a phenomenological research effort. Five interviews were conducted with four women and one man, from four associations in Gavle municipality. The interviews were transcribed verbatim and analysed with a thematic analysis. The result showed that the staff's perceptions about their work were that the work being conducted was a good method of promoting well-being and contributing to a sense of context for remedying mental ill health. Cooperation with community actors was also a key in their work and made it possible to reach the children and adolescents who were the target group for health-promoting cultural activities. The difficulties perceived were lack of economics, information and structural changes, which made it difficult to implement, follow up and continue their work. The conclusion was that the work with health promoting activities was perceived as a method of integration as well as promoting health. There was also a consensus that the work performed had a good effect in bringing children and young people's families closer to the Swedish society. The obstacles discovered were structural changes, lack of information and too little of economy. One key to success was the cooperation in the local community which made it possible to reach the group.

Objective: This study compared usage patterns of two different electronically controlled sit-stand tables during a 2-month intervention period among office workers.

Background: Office workers spend most of their working time sitting, which is likely detrimental to health. Although the introduction of sit-stand tables has been suggested as an effective intervention to decrease sitting time, limited evidence is available on usage patterns of sit-stand tables, and whether patterns are influenced by table configuration.

Methods: Twelve workers were provided with standard sit-stand tables (non-automated table group) and 12 with semi-automated sit-stand tables programmed to change table position according to a pre-set pattern, if the user agreed to the system-generated prompt (semi-automated table group). Table position was monitored continuously for two months after introducing the tables, as a proxy for sit-stand behavior.

Results: On average, the table was in a “sit” position for 85% of the work-day in both groups; this did not change significantly during the 2-month period. Switches in table position from sit to stand were, however, more frequent in the semi-automated table group than in the non-automated table group (0.65 vs. 0.29 hr-1; p=0.001).

Conclusion: Introducing a semi-automated sit-stand table appeared to be an attractive alternative to a standard sit-stand table, since it led to more posture variation.

Application: A semi-automated sit-stand table may effectively contribute to making postures more variable among office workers, and thus aid in alleviating negative health effects of extensive sitting.

Background: Introduction of sit-stand tables has been proposed as an initiative to decrease sedentary behavior among office workers and thus reduce risks of negative cardiometabolic health effects. However, ensuring proper and sustainable use of such tables has remained a challenge for successful implementation. Objective: We developed a new system to promote and sustain the use of sit-stand tables. Methods: The system was programmed to change the position of the table between “sit” and “stand” positions according to a regular pre-set pattern, if the user agreed to the system-generated prompts prior to each change. The user could respond to the system-generated prompts by agreeing, refusing or delaying the changes by 2 minutes. We obtained user compliance data when this system was programmed to a schedule of 10 minutes of standing after every 50 minutes of sitting. Compliance was investigated in nine office workers who were offered the semi-automated sit-stand table for two months. Results: On average, the system issued 12-14 alerts per day throughout the period. Average acceptance rate ranged from 75.0-82.4%, and refusal rate ranged from 11.8-10.1% between the first and eighth weeks of intervention (difference not statistically significant). During the first week after introduction, the table was in a standing position for 75.2 min on average, increasing slightly to 77.5 min in the eighth week. Conclusion: Since the workers were essentially sitting down before the table was introduced, these results suggest that the system was accepted well, and led to an effective reduction of sitting during working hours. Users also reported that the system contributed positively to their health and wellbeing, without interrupt their regular work, and that they would like to continue using the sit-stand table even beyond the two-month period, as part of their regular work. Compliance beyond two months of use, however, needs to be verified.

Background. There is increasing evidence that sedentary behaviour during the workday is associated with negative health effects. In this context, interventions to reduce total sedentary time and breaking up periods of continuous sitting during computerized office work are urgently needed. Several reviews conclude that introducing sit-stand stations may lead to positive effects, but they also state that long-term interventions in real occu-pational settings are still rare. Therefore, the aim of this study was to investigate usage of sit-stand tables among Brazilian office workers during an intervention lasting two months.

Methods.Nine office workers (6 females, 3 males; age 42 [SD 12] years) participated. The workers received traditional sit-stand tables and ergonomics information. They then used the workstation for two months. The tables were furnished with a system that recorded and kept track of table use during the intervention period. Table use early and late in the intervention period was compared using the Wilcoxon signed-rank test for repeated measurements.

Results. In the beginning of the eight-week intervention period, workers, in median, changed table position 2.4 (1.9 – 4.7) times per day, decreasing to 2.3 (1.0 – 3.3) times at the end (P=0.09). Moreover, we also found a non-significant decrease in total time stand-ing per day, from 88.6 (67.4 – 94.3) minutes to 58.8 (33.1 – 95.7) minutes (P=0.31).

Discussion. Two months after introducing sit-stand tables, some decrease in usage could be seen, if not statistically significant. Based on this, we emphasize that introduction of sit-stand tables should be accompanied by continued encouragement of the workers, preferably informed by a personalized follow up of actual use.

Postures and muscle activity in the upper body were recorded from 50 academics office workers during 2 hours of normal work, categorised by observation into computer work (CW) and three non-computer (NC) tasks (NC seated work, NC standing/walking work and breaks). NC tasks differed significantly in exposures from CW, with standing/walking NC tasks representing the largest contrasts for most of the exposure variables. For the majority of workers, exposure variability was larger in their present job than in CW alone, as measured by the job variability ratio (JVR), i.e. the ratio between min–min variabilities in the job and in CW. Calculations of JVRs for simulated jobs containing different proportions of CW showed that variability could, indeed, be increased by redistributing available tasks, but that substantial increases could only be achieved by introducing more vigorous tasks in the job, in casu illustrated by cleaning.

Sedentary behaviors in office workers has become a major public health concern and several initiatives have been proposed to break up sedentary behavior patterns during the performance of computer-intensive office work. Among such initiatives, the use of sit-stand workstations has been suggested to be one of the most promising by recent reviews. However, there still is only limited scientific evidence showing how effective sit-stand workstations are, in reducing sedentary behaviors and also documentation of their sustainability of use in studies of regular office work (i.e. as the “newness” of the system wears off, with time since introduction). This study aimed to document user behaviors and compare the use of two sit-stand workstation based interventions among two groups of administrative office workers: an “autonomous” group in which these workstations were introduced following some general ergonomic guidelines, and another “feedback-system” group in which the sit-stand tables were furnished with a semi-automatic reminder system, programmed to raise the table to a high (i.e. standing) position for 10 minutes after every accumulated 50 minutes of the table being in a low (i.e. sitting) position, i.e. to result in about 83% sitting per day. In addition, the sustainability of the use of these two kinds of sit-stand workstation interventions over two continuous months since their introduction was also studied. The results averaged over two months of usage of the two interventions showed that the percentage (%) sitting time was 87.4 (84.9-89.2) on average in the autonomous group and 84.0 (83.5-85.4) on average in the feedback-system group (P=0.001), and the frequency of switches between sitting and standing was 0.3 (0.2-0.3) per hour in the autonomous group and 0.7 (0.6-0.7) per hour in the feedback-system group (P=0.001). Thus, the sit-stand table system integrated with the automatic reminder system led to more reduction in sitting time and more switches in posture between sitting and standing as compared to the traditional sit-stand table, and behaviors of both groups were seen to be sustained over the 2-month intervention period (no difference across time for any of the variables tested for any group).

Suicide is a leading cause of death world-wide. However, adolescent suicidal behavior is a neglected public health issue, especially in low-income countries such as Bangladesh. The study was conducted to estimate the prevalence of suicidal ideation among adolescents in a rural community and to examine factors associated with suicidal ideation. A cross-sectional survey was carried out in 2013 among 2,476 adolescents aged 14–19 years, selected randomly from a rural community of Bangladesh. An adapted version of the WHO/SUPRE-MISS questionnaire was used to collect data in the Raiganj sub-district. A two stage screening was performed to identify the suicidal ideation cases. It was found that the life-time prevalence for suicidal ideation was 5 percent among adolescents. The majority of the adolescents with suicidal ideation were females 66 (52.8%), unmarried 103 (82.4%), and students 92 (73%). Suicidal ideation was statistically significantly associated with age, education, occupation, living with parents or others, and house ownership. Respondents who were aged 18–19 years, had secondary school certificate (SSC) and secondary school certificate (HSC) or higher education, were day laborers, had own house, and do not lived with parents had odds ratios of 2.31 (CI 1.46–3.65), 2.38 (CI 1.51–3.77), 4.15 (CI 2.41–7.14), 0.28 (CI 0.13–0.60), 0.14(CI 0.05–0.35), and 1.80 (CI 1.07–3.03), respectively. Among adolescents, the prevalence of life-time suicidal ideation was moderately high. Age, education, occupation, house ownership, and living with parents were statistically significantly associated with suicidal ideation. It is important to design and implement effective community based suicide prevention programs for adolescents in Bangladesh.

Background: Suicide is a leading cause of death world-wide and becoming a public health concern among adolescents. However, adolescent suicidal behaviour is a neglected public health issue, especially in low-income countries such as Bangladesh. Of great importance is the understanding of which factors might be related to this growing public problem.

Objective: To examine the relationship between parental socio-economic position and suicide ideation among adolescents in rural Bangladesh

Methods: A cross-sectional survey was conducted in 2013 among 2,476 adolescents, aged 14-19 years, selected randomly from a rural community of Bangladesh. An adapted version of the WHO/SUPRE-MISS questionnaire was used to collect data in the Raiganj sub-district, which is a surveillance area of the Centre for Injury Prevention and Research, Bangladesh (CIPRB).

Descriptive statistics and binary logistic regression analyses were used to analyze the data. Comparisons of proportions between groups were carried out using the χ2 test. Multivariate logistic regression analysis was used to examine the relationship between parental co-variants and suicidal thoughts among adolescents. The significance level was set atp <0.05. All analyses were performed using SPSS 20.

Results: The majority of parents had education only up to primary school (mothers 58.7% and fathers 49.5%). Most of them were farmers (53.3% of fathers) and housewives (96.5% of mothers). Monthly income and expenditure of the adolescent’s parents were mainly upto 10,000 taka only. Suicidal ideation is more common among adolescents of low income group parents 104 (5.5%) and who were not living with their parents 18 (8.2%). Adolescent’s suicidal ideation was found to be significantly associated with education, marital status and house ownership of their parents. Not being able to live with their parents was also a significant factor. Parents who received education up to SSC had odds ratio of 2.10 (1.21,3.64) and 1.92 (1.15, 3.23) for mothers and fathers respectively. Parent’s income or expenditure was not associated with adolescent’s suicidal ideation. Adolescent’s suicidal ideation of single parents had higher odds (OR 3.00, CI 1.75-5.19) in comparison to adolescents who had both parents. Adolescents whose parents owned a house and who weren’t living withtheir parents had odds ratios of 0.14 (0.05,0.35), and 1.80 (1.07,3.03) respectively. After adjusting for other covariates parents’ marital status and house ownership significantly associated with the adolescent suicide ideation.

Conclusion: Parental socio-economic position was asso-ciated with suicidal ideation. Adolescent with single parents were more likely to report suicidal ideation. Low parental education and socio-economic status, marital status, house ownership, not living with parents at home as well as adolescent loneliness were the important factors for suicidal ideation.
